This is the middle shroud on a Quantum power chair; your feet would sit on it when installed. The best way to match you up with the correct part for your Quantum would be to reference the serial number of the unit. Generally, they are found on a sticker on the rear frame of the unit. It will start with the letter 'J' and be 14-digits long. You can reach us during business hours at 800-798-0325 or email us at contact@monsterscooterparts.com to provide the unit's serial number so we can help you find the correct part.
